Looks like my tach is dead. Looking at VDO's Viewline tach with programable rev warning and hour meter. I want to keep the look of the rest of the gauge cluster but havent found a vintage OEM tach. Just looking for thoughts before I pull the trigger.

I want to open up my current unit to see if I can find the bad component but in reality not having the time I better just R^2 it and move on....
